FAQ
Where can I get service and/or consumable parts for Kemppi equipment?

You can get service and consumables from your nearest Kemppi representative. Please see our representatives near you.

How can I find the closest Kemppi service workshop near me?

You can find the closest repair workshop from our map search.

What kind of a warranty does Kemppi equipment have?

Kemppi welding equipment is designed and tested for professional industrial environments. As a guarantee of high quality, we offer our customers a global warranty up to three years. 

For full details, see Kemppi Warranty.

Mains and generator use, what do I need to do if anything?

If no mains connection is available, you can use FastMig X 350 and X 450 on a generator. The minimum recommended generator output is 35 kVA. The greater the output, the more stable is the FastMig X power source operation.

On my FastMig X machine, what is the normal cooling fan sequence, start up and in operation?

FastMig X power sources incorporate two simultaneously operating fans.

  • The fan is started momentarily when the main switch is turned into position I.
  • The fan will start during welding as the machine reaches operational temperature, and it will continue running for 1 to 10 minutes after the welding has stopped, depending on the welding cycle completed.
How to change gas cooled / water cooled selection?

The factory default setting for FastMig X is AUTO. If a cooling unit is not connected and the operator tries to establish air-cooled operation together with an air-cooled gun, Err 27 is displayed. To establish air-cooled operation, select cooler ‘OFF’.

This is done in the ‘System Config Menu’ as follows: Press the Menu button on the X 37 power source panel. Move the menu display arrow (via panel's left-hand up-down arrow keys) to select ‘System Config Menu’ and then press the select button. Choose ‘Water Cooling:Auto’ and change via control knob to setting ‘Water Cooling:OFF’, then press Back/Exit. Cooler will then be set to the ‘OFF’ state for air-cooled operation. Reset power source via on/off switch and continue welding.

When selected, the operation of the cooling unit is automatic, starting when welding commences. When welding stops the pump will continue operation for approx. 5 min, so reducing the gun and the cooling liquid to ambient temperature.

Intelligent, flexible, upgradable

Kemppi's FastMig X product series offers highly specialized welding solutions and superior welding quality for demanding industrial applications. It features three alternative high-end configuration recommentations for three different purposes: FastMig X Regular for robust workshop use a MIG/MAG pulse welding, mainly for welding thick plates, FastMig X Pipe for pipe and root welding and FastMig X Intelligent for demanding welding applications, for all metals and processes, including welding of thin sheets.

All configurations are equipped with either the FastMig X 350 or the FastMig X 450 power source, which is a multi-process CC/CV power source that is ideal for synergic and pulsed MIG/MAG welding, MMA welding, and TIG welding. Used in configuration with WFX wire feeders, they form a welding system that easily meets every welding need and the quality management requirements of any metal fabrication workshop. Additionally, all three configurations come with the Cool X cooling unit.

Benefits

  • Multi-process power solution: MIG, 1-MIG, pulsed MIG, MMA, and TIG
  • Arc Mobile Control brings flexible way to use and control the welding machine
  • WiseRoot+ for optimized root welding
  • WiseThin + for optimized sheet and position welding: Mixed gas quality with lower cost CO2 shielding gas
  • Precise arc voltage function measures and shows the actual arc voltage on the display
  • Save time by combining two wire feeders on the same power sourcefor alternative filler wires
  • SuperSnake subfeeder connectivity for maximum reach
